A train traveling at a uniform speed passes a 455 meter long platform in 17 seconds and another platform. 175 meter long in 10 seconds. find the length and speed of the train. ​

Answer 1

Step-by-step explanation:

let the length of train be x

445+x÷17 = 175+x÷10

445+x= (175+x)1.7

445+x=297.5+1.7x

x-1.7x=297.5-445

x = 147.5÷0.7
